The present disclosure relates to the technical field of data storage, and provides an IO request processing method, apparatus and system for multi-path storage and a storage medium, which are intended to improve IO efficiency of processing requests. When the method is applied to a storage system, the method includes: dividing a target volume to obtain a plurality of segments; determining a mapping relationship between the plurality of segments and a plurality of storage nodes, the mapping relationship being used for identifying an optimal storage node mapped by a segment in the plurality of storage nodes; detecting states of the plurality of storage nodes; adjusting the mapping relationship on the basis of respective detected state parameters of the plurality of storage nodes and/or path switching information sent by a host; and sending the adjusted mapping relationship to the host, so that the host, on the basis of the adjusted mapping relationship, sends an IO request for a segment to a path device corresponding to the optimal storage node.
